Rhino-Rack X Tray car roof cargo basket. Besides being one of the coolest looking baskets out there, the X Tray cargo basket fits the widest range of vehicles. It is the perfect choice for aftermarket roof racks, or if you may want to switch cars in the future. The key to the X Tray's compatibility are: it has really nice universal mounting brackets, and unlike other roof baskets, the locations of the mounting brackets are continously adjustable. Most cargo baskets have the tubing on the floor of the basket running cross-wise of the basket and the brackets can only be installed in specific locations. On the X Tray cargo basket the tubing runs parallel to the basket and the mounting brackets slide on the tubing. The X Tray can be installed on crossbars from 21 to 30 inches apart. The universal mounting brackets accomodate aerodynamic bars up to 3.5 inches wide and 1.3 inches tall. The X Tray is black powder coated steel; two piece construction. This is the size small X Tray, but it is kind of an Aussie small, this basket is 47.2 x 35.4 inches (most regular sized baskets are about 44 x 39). The load capacity of the basket is 165 lbs, but your roof rack may be less, always go with the lowest weight limit. This product does NOT fit Rhino Rack HD bars. Manufacturer's part number: RMCB01
